Re: Looking for an MPF III keyboard

["Mark Cummings" <NOTfigjams@primus.com.au>]

David,

My MPF III had a couple of EPROMs in place of the ROMs, with a toggle switch
wired up to what I assume would be one of the address lines, so it can
select the other half of the ROM. I havn't had time to find out what is
going on, but so far proven that only one half of the EPROM works (the MPF
III half) Do you know what could be or could have been in the other half ?
